HSD Coilover


HSD HR Coilovers (also called HSD Monopro Coilovers in other countries) are premium grade monotube coilovers by HSD for under $1500.

Why choose a monotube coilover over a dualtube?

Monotube designs offer superior height and damping adjustability, a wider pressure area for more precise damping, no installation restrictions, higher oil capacity, improved heat dissipation, and resistance against aeration. Monotube coilovers are the suspension product of choice for performance enthusiasts. HSD Coilovers are designed for both race and street use. Ultimately, monotube designs are of a higher production quality than their dualtube counterparts, which are designed for cheap mass production.
